Most HVAC systems last 15-25 years with proper maintenance. Air conditioners typically last 15-20 years, furnaces 15-30 years, and heat pumps 10-15 years. Regular maintenance, quality installation, and proper sizing can extend your system's lifespan significantly.

Air conditioners freeze due to: restricted airflow from dirty filters or blocked vents, low refrigerant levels, dirty evaporator coils, or malfunctioning blower motors. Turn off your AC immediately if you notice ice buildup and allow it to thaw completely before calling a technician to diagnose the underlying cause.

Choose filters based on your needs: MERV 8-10 for basic dust and pollen protection (most homes). MERV 11-13 for allergy sufferers and better filtration. MERV 14-16 for maximum filtration (may restrict airflow in some systems). HEPA filters for severe allergies (usually require system modifications). Check your system's maximum recommended MERV rating before upgrading.

Proper HVAC sizing requires a professional Manual J load calculation considering: home square footage, ceiling height, insulation levels, window size and orientation, local climate, number of occupants, and heat-generating appliances. Oversized systems short-cycle and waste energy; undersized systems run constantly and can't maintain comfort. Never size based on square footage alone.
